Hot Module Replacement (HMR)
Pinia supports HMR to edit stores without page reload, preserving existing state.
Setup
Add this snippet after each store definition:
import { defineStore, acceptHMRUpdate } from 'pinia'
export const useAuth = defineStore('auth', {
// store options...
})
if (import.meta.hot) {
import.meta.hot.accept(acceptHMRUpdate(useAuth, import.meta.hot))
}
Setup Store Example
import { defineStore, acceptHMRUpdate } from 'pinia'
export const useCounterStore = defineStore('counter', () => {
const count = ref(0)
const increment = () => count.value++
return { count, increment }
})
if (import.meta.hot) {
import.meta.hot.accept(acceptHMRUpdate(useCounterStore, import.meta.hot))
}
Bundler Support
- Vite: Officially supported via
import.meta.hot - Webpack: Uses
import.meta.webpackHot - Any bundler implementing the
import.meta.hotspec should work
Nuxt
With @pinia/nuxt, acceptHMRUpdate is auto-imported but you still need to add the HMR snippet manually.
Benefits
- Edit store logic without losing state
- Add/remove state, actions, and getters on the fly
- Faster development iteration
